Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product stacking system in which a worker quickly packs products sorted by order stores or cardboard cases containing the products into a carrier truck such as a car truck.

Due to the aging society and the decrease in the working-age population in recent years, it has become difficult to secure a labor force at distribution centers. In addition, personnel costs have continued to rise, as they are putting additional pressure on reducing logistics costs.
General distribution centers in the intermediate distribution industry, including wholesale businesses, have the function of shipping products individually or in case units in accordance with order information from customers, but the productivity per person in such work is high. At present, however, the number of cases is 150 to 200 cases per hour. By dramatically increasing this productivity, it contributes to improving the productivity of the entire distribution and also reduces distribution costs. It will be a high need in the future labor shortage society.

  Products are usually sorted according to the customer's order into a carrier truck such as a car truck for each customer's store and delivered to the store by truck. In the process of putting it in that state, the products stored in each area of the center are collected (batch) in a group of a plurality of stores in each area, batch picked, and put into a facility such as the nearest conveyor.

  The loaded products are usually sorted automatically by each store via a sorting machine having the number of stores to be processed in the batch, and finally, the products are manually loaded on the carriage. At that time, unless all the products in the batch have flowed, the next batch cannot be moved.

  In addition, the productivity per person at the time of packing is 150 cases to 200 cases / hour at the maximum including sub-operations (operations such as replacement when the carriage is full, loss between batches, product replacement at the time of packing). is there.

  In addition, as in Patent Document 1 and Patent Document 2, there is also an automatic system in which goods are picked and sorted into each store collectively by full automatic operation, and the goods are loaded on a carrier truck and shipped.

  However, in the case of the fully automatic product shipping and sorting system as in Patent Document 1 or Patent Document 2, it is very difficult to utilize the equipment of the existing distribution center, and the construction of the control system and the equipment to make everything fully automatic. There is a possibility that enormous cost and labor will be required to maintain the system. Furthermore, since it is fully automatic, there is a risk that the flexibility of the system will be poor.

  Further, in the conventional manual product packing work, in the process of manually packing the products on the carrier, it is necessary to stack products with a product weight of 3 to 12 kg / piece from the height below the knee to the height of the head. I have to. Also, when a heavy product flows after a light product, the replacement work must be performed so that the product is not crushed. When the trucks being packed are full of products, the empty trucks must be replaced because the trucks must be replaced with empty trucks, and the trucks are discharged to the specified position. It must be transported and set from the storage position to the packing position. Further, as described above, in the operation of collectively picking up a plurality of stores (batch) for each area and performing batch picking, a batch-to-batch loss occurs during processing of the current batch to the next batch.

  An object of the present invention is to provide a product stacking system capable of improving work efficiency and reducing the burden of product packing operations on workers.

  The product stacking system 10 is provided with a plurality of product stacking mechanisms 20 for packing products A sorted according to order stores on a carrier B so as to surround a work booth C, and in this embodiment, 4 The merchandise stacking mechanism 20 is one separate order store. The product stacking system 10 is a system for one worker, and the product stacking systems 10 are installed in parallel according to the capacity of the distribution center and the number of order stores, that is, the number of sorting.

  The product stacking mechanism 20 is provided with a carrier cart supply / delivery mechanism 30, a product supply mechanism 40, and a slide base 50. An operator slides the product A supplied from the product supply mechanism 40 on the slide base 50. The carts are stacked so as to be pushed into the cart B set in the cart supply / delivery mechanism 30. The height at which the products A are stacked on the carrier B is set to be the same as the slide table 50 by the carrier supplying / discharging mechanism 30.

  The transport vehicle supply / delivery mechanism 30 is a transport vehicle supply mechanism 31 that supplies the transport vehicle B to the work booth C, an elevating mechanism 32 for loading the transport vehicle B while lowering the transport vehicle B, and a lowering after the product A is loaded. It has a payout mechanism 33 for paying out the transported carriage B.

  The trolley supply mechanism 31 is configured to be transported by the weight of the transport trolley B and supplied to the elevating mechanism 32, and therefore is provided with an inclination. Although the trolley supply mechanism 31 may be electrically driven by a belt conveyor or the like, the self-weighted conveyance supply mechanism as in the present embodiment has an advantage that it can contribute to power saving and that the structure of the mechanism can be simplified. .

The carriage supply mechanism 31 is provided with a stopper 31a immediately before the transport carriage B is supplied to the lifting mechanism 32, and the stopper 31a operates in conjunction with the lifting operation of the lift mechanism 32 to move the transport carriage B one by one. It is a mechanism that is set in the lifting mechanism 32.
In this embodiment, when the elevating mechanism 32 rises and reaches a predetermined position, the stopper 31a is turned off and the carriage B is set, and when it starts descending, the stopper 31a is turned on and the carriages B connected to the rear side are The structure is such that it is conveyed by its own weight to the position of the stopper 31a and stops.

  The elevating mechanism 32 is a mechanism that mounts and fixes the transport carriage B on a mounting table 32a in the form of a flat plate tray and moves up and down. As shown in FIG. 2, an empty carrier B is supplied at the rising end of the lifting mechanism 32, and when the carrier B is supplied, the height of the bottom of the carrier B and the upper end of the slide table 50 are the same as in FIG. As shown in FIGS. 2B to 2D, as the products A are stacked, the height of the upper end of the products A that have been stacked is lowered so as to be the same as the height of the upper end of the slide table 50. Eventually, the carrier B, on which the goods A have been stacked at the descending end, is delivered.

When the operator pushes the lowering switch 32b shown in FIG. 3D, the mounting table 32a of the elevating mechanism 32 descends, and the carriage B also descends. The lowering switch 32b operates even if it is pushed by hand, and has a shape devised so that it can be pushed even on the thighs. The operator has a mechanism to stop the descending by releasing the descending switch 32b after the operator descends until the upper end of the stacked products A reaches the height of the upper end of the slide table 50. In addition, although the lowering switch 32b is used in the present embodiment, a configuration in which sensors such as a photoelectric sensor measure the stacking height of the products A and the operator automatically pushes down the button to descend to the next stacking height. May be
When the carrier vehicle B is paid out, the mounting table 32a of the lifting mechanism 32 is automatically raised.

  In this embodiment, the elevating mechanism 32 descends as the carriage B is loaded with products, so that the stacking height of the carriage B and the height of the slide table 50 are always the same, and the height at the time of dispensing, which is the descending end. Since it is the ground of the distribution center, the work booth C is installed at a predetermined height (about 2 m in this embodiment) from the ground according to the height of the carrier B. If the work booth C is the ground, the payout position will be constructed underground.

  The delivery mechanism 33 is provided with an inclination like the trolley supply mechanism 31, and the delivery vehicle B on which the products A have been loaded is delivered by its own weight, and leads to the subsequent step of loading on a truck.

  The merchandise supply mechanism 40 is for supplying merchandise A, which is sorted according to the order store in advance, to the slide table 50, and in this embodiment, it is a self-weighted conveyance system that saves power and cost, but is not limited to this. It may be a roller conveyor.

The slide table 50 is movable while sliding the product A when the product A supplied from the product supply mechanism 40 is moved to the transfer car B set in the elevating mechanism 32 of the transfer car supply / delivery mechanism 30. Since the ball casters 51 are embedded in the slide table 50, the operator can easily move the product A without sliding it without lifting it, and push the product A into the carriage B for loading. it can. Further, since the height of the slide base 50 is the height of the waist of the worker, the work can be performed without bending and the burden on the body can be minimized.
In addition, since the elevating mechanism 32 allows the products to be stacked at a waist height where the burden is always small, it is possible not only to reduce the burden on the worker but also to significantly improve the working efficiency.

  In addition, when the product A is small in size or light in weight at the time of loading, it may be crushed if a heavy product is placed on the product A. Therefore, the temporary placing table 60 is placed at the same height as the slide table 50. It is possible to set aside and temporarily put it there and reload it again. In the present embodiment, the temporary placing table 60 has a size such that one product can be temporarily placed, but the present invention is not limited to this, and a plurality of temporary placing tables may be used.

  The product stacking system 10 of this embodiment is provided with four product stacking mechanisms 20. Since the product can be immediately moved to the adjacent product loading mechanism 20 and the loading operation can be started while the loading operation is completed after the loading operation is completed by the product loading mechanism 20 at one place, It is possible to prevent a decrease in the packing work efficiency due to the work of setting and paying out the carriage B as described above. The number of merchandise stacking mechanisms 20 may be two, three, five, or the like depending on the processing capacity of each distribution center, but it is advisable to install them with a margin so as not to exceed the processing capacity of the worker.

  Further, since the work booth C is provided in a space-saving manner so that the elevating mechanism 32 of the transport vehicle supply / delivery mechanism 30, that is, the loading position is close to the center of the work booth C, the product loading mechanism 20 for the worker is provided. The distance traveled between them can be minimized, which contributes to reducing the burden on workers.

  When a loading experiment was performed with the system configuration of this example, the hourly productivity per person was 800 to 1000 cases. In the conventional transfer cart replacement work, the hourly productivity per person was 150 to 200 cases. As a result, this system was able to greatly improve work efficiency.

  In the case where the worker packs the products into the carrier trucks at each order store in a collection site such as a distribution center, the packing work can be performed efficiently, and thus the number of workers can be increased to pack more products.
